Create a simple mesh xy NOC

[AdDraw]

To move further into creation of a NOC for the purpose of the Master Thesis what needs to be done first is a base.

The base will be simple mesh NOC with XY algorithm.

1. [x] create a simple Mesh xy switch
2. [x] create a unitary testbench that will check switch's functionality
   • [x] collect small performance metrics like latency
3. [x] make the switch have a configurable number of PORTs and verify
4. [x] create a scalable NxN NOC made out of these switches
5. [x] create a testbench that will exercise the switches
6. [x] collect performance metrics for the NOC
